So last night my partner and me argued, (not relay argued, but he was talking to me like sh** so I went to chill upstairs out his way. He calls me down to change the cable at the back of the TV as I have smaller hands than him and apparently he cant do it (although he manages when I'm not around). I do it while he is in the kitchen. And go bk upstairs and whilst checking my kid are sleeping OK I hear him say wrong bloody cable you dickhead, it was quite loud. So I sort out my child who had woken up and then went downstaors I was literally five min max, I ask him did you call me a dickhead and why cos I did the cable as he had asked. He laughed and said what are you on about, your crazy I never said anything...and suggested maybe I needed an early night. I know he said it. It was said loud enough.... Is this gaslighting or am I being over sensitive? My brother said i was over sensitive.
